CROSS REFERENCE TO RELATED APPLICATION(S)

This application is a bypass continuation of International Application No. PCT/KR2022/021610, filed on Dec. 29, 2022, which is based on and claims priority to Korean Patent Application No. 10-2021-0191348, filed on Dec. 29, 2021, in the Korean Intellectual Property Office and Korean Patent Application No. 10-2022-0033605, filed on Mar. 17, 2022, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties.

BACKGROUND 1. Field

This disclosure relates to a display apparatus and a controlling method thereof and more particularly, to a display apparatus that operates and displays a screen saver and a controlling method thereof.

2. Description of Related Art

Recently, various types of display apparatuses have been developed and distributed.

In particular, as display apparatuses get bigger and have higher resolution, the power consumption of the display apparatus proportionally increase.

When a display apparatus does not operate for a certain period of time or a user does not use the display apparatus, the display apparatus may be switched to a standby mode (power saving mode). In such a standby mode, a screen saver may be operated to minimize power consumption of a display panel which is a main power consumption component of the display apparatus.

In addition, a screen saver may also be operated to offer a solution to the problem of shortened lifespan of a light emitting device of the display apparatus, the burn-in issues, etc.

However, when a screen saver operates irrespective of the user’s intention or the screen saver operates regardless of the operation (current state) of the display apparatus, there is a problem in that it causes trouble and inconvenience.

In order to prevent such inconvenience, according to the prior art, when operating a screen saver, a method of inquiring whether to run the screen saver to an application (or program) is used, but there is a problem in that it is not easy to monitor which application to which such an inquiry should be made.

Accordingly, there is a demand for a method for more simply determining whether to operate a screen saver in relation to the user’s intention and the operation of the apparatus.

According to another embodiment, the display apparatus 100 may include at least one of medical devices (e.g., various portable medical measurement devices (e.g., a blood glucose monitoring device, a heartbeat measuring device, a blood pressure measuring device, a body temperature measuring device, and the like)), a magnetic resonance angiography (MRA), a magnetic resonance imaging (MRI), a computed tomography (CT), scanners, and ultrasonic devices, etc.), navigation devices, global navigation satellite system (GNSS), event data recorders (EDRs), flight data recorders (FDRs), vehicle infotainment devices, electronic equipment for vessels (e.g., navigation systems, gyrocompasses, and the like), avionics, security devices, head units for vehicles, industrial or home robots, drones, automatic teller’s machines (ATMs) of banking institutions, points of sales (POSs) of stores, or internet of things (e.g., light bulbs, various sensors, sprinkler devices, fire alarms, thermostats, street lamps, toasters, exercise equipment, hot water tanks, heaters, boilers, and the like).

According to an embodiment, a plurality of display modules may be combined to implement one display apparatus (that is, the display apparatus 100).

The display apparatus 100 according to an embodiment may include a plurality of self-luminous elements. Here, the self-luminous element may be at least one of a Light Emitting Diode (LED) or a micro LED.

For example, the LED may include a RED LED, a GREEN LED and a BLUE LED. In addition, the LED may further include a White LED in addition to the RGB LED. According to an embodiment, the micro LED is an LED having a size of about 5 to 100 micrometers, and it is a small light emitting element that emits light by itself without a color filter.

Accordingly, the display apparatus 100 may receive a user input (or a control signal corresponding to the user input) from an external device (e.g., a remote control device 200), or may receive a user input from various types of input devices (e.g., a touch screen, a keyboard, a mouse, etc.).

The display apparatus 100 according to an embodiment may operate and display a screen saver when a user input is not received for a threshold time.

According to an embodiment, the display apparatus 100 may display a screen saver in order to protect a display provided in the display apparatus 100 (e.g., in order to resolve a burn-in issue of a panel), by displaying a screen 10 corresponding to the screen saver.

For example, the screen 10 corresponding to the screen saver may mean a screen or screens, or an image or images, that are pre-stored by the manufacturer or saved by a user in the display apparatus 100, etc., in order to mitigate the burn-in of a plurality of self-luminous elements included in the display apparatus 100.

In addition, the display apparatus 100 may display the screen saver, i.e., display the screen 10 corresponding to the screen saver, by displaying the screen saver in order to efficiently manage power consumption of the display apparatus 100.

For example, there is a need for efficiently managing power consumption of the display apparatus 100 as the display apparatus 100 has higher specification, higher performance, higher output, and the like.

According to an embodiment, when the display apparatus 100 does not operate for a predetermined time (or a threshold time) or a user input is not received in the display apparatus 100 for a predetermined time, the display apparatus 100 may operate or switch to a mode for minimizing power consumption. Here, the mode for minimizing power consumption may include a standby mode, a power saving mode, a mode for operating a screen saver, and the like.

The screen 10 corresponding to the screen saver is a screen for minimizing power consumption of a display (e.g., a panel) provided in the display apparatus 100, and may include a still screen or an animation screen.

The processor provided in the display apparatus 100 according to an embodiment may count time for operating the screen saver after a user input is received, and when the counted time corresponds to a threshold time, may display a screen corresponding to the screen saver by operating the screen saver, i.e., display the screen saver.

Here, the threshold time, e.g., timeout time, inactivity time, etc., is a time arbitrarily set by a manufacturer, a user, and the like, and can be changed. For example, when the threshold time is 5 minutes, the processor counts time for displaying the screen saver after a user input is received through the remote control device 200 and when the counted time reaches the threshold time, that is, 5 minutes, the processor may display the screen 10 by operating the screen saver, i.e., display the screen saver.

Meanwhile, according to various embodiments, the display apparatus 100 may not display the screen saver even if a user input is not received for a threshold time. Hereinafter, an embodiment for not displaying the screen saver will be described through various drawings.

FIG. 2 is a block diagram provided to explain configuration of a display apparatus according to an embodiment.

According to FIG. 2 , the display apparatus 100 includes a display 110 and a processor 120.

The display 110 according to an embodiment may be implemented as various types of displays such as liquid crystal display (LCD), organic light-emitting diode (OLED), Liquid Crystal on Silicon (LCoS), Digital Light Processing (DLP), quantum dot (QD) display panel, quantum dot light-emitting diodes (QLED), Micro light-emitting diodes (µLED), Mini LED, etc. Meanwhile, the display 110 may be implemented as a touch screen combined with a touch sensor, a flexible display, a rollable display, a 3D display, a display in which a plurality of display modules are physically connected, etc.

The processor 120 is electrically connected to a memory (not illustrated), and controls the overall operations of the display apparatus 100.

According to an embodiment, the processor 120 may be implemented as a digital signal processor (DSP) for processing digital image signals, a microprocessor, or a time controller (TCON), but is not limited thereto. The processor 120 may include at least one of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a communication processor (CP), an ARM processor, or an Artificial Intelligence (AI) processor, or may be defined as the corresponding term. Further, the processor 120 may be implemented as a System on Chip (SoC) integrated with a processing algorithm, a large scale integration (LSI), or in the form of a field programmable gate array (FPGA). In addition, the processor 120 may perform various functions by executing computer executable instructions stored in a memory 130.

Firstly, the processor 120 according to an embodiment may count time for operating the screen saver after a user input is received, and when the counted time corresponds to the threshold time, may control the display 110 to display a screen corresponding to the screen saver.

When a reset request regarding the counted time is received from an application that is being executed in the display apparatus 100, the processor 120 according to an embodiment may reset the counted time. Subsequently, the processor 120 may recount time for operating the screen saver.

For example, the processor 120 may count time for operating the screen saver after a user input is received (that is, time for operating the screen saver may sequentially increase from 0 second).

Subsequently, when a reset request for the counted time is received from the application, the processor 120 may reset the counted time and recount time for displaying the screen saver (that is, time for displaying the screen saver may sequentially increase from 0 second again).

Subsequently, when the recounted time corresponds to the threshold time (e.g., when the recounted time reaches the threshold time), the processor 120 may control the display 110 to display a screen corresponding to the screen saver.

FIG. 3 is a view provided to explain a reset request of an application according to an embodiment.

Referring to FIG. 3 , the application that is being executed in the display apparatus 100 may transmit a reset request for the counted time for displaying the screen saver.

For example, the display apparatus 100 may use a standardized general-purpose system (e.g., a general-purpose operating system (O/S)), or a dedicated system of the display apparatus 100 (e.g., a dedicated O/S). The system used by the display apparatus 100 may provide an environment in which various services and various applications can be added, deleted, amended, or updated.

The application according to an embodiment means a program capable of performing various functions according to the purpose of the application, and can be implemented as various programs such as content player, e-mail, web browsing, banking, game, word processor, photo editing, etc.

For example, the application may be a content player that outputs video contents, and may transmit a reset request so that the video contents are reproduced seamlessly without displaying the screen saver even if there is no user input (e.g., even if a user input is not received for the threshold time) while the video contents are reproduced.

For example, the content player may transmit a reset request in a period less than the threshold time, and since the processor 120 resets counted time according to a reset request before the amount of time during which a user input is not received (e.g., the counted time) reaches the threshold time, the processor 120 may not display the screen saver.

In addition, the system used by the display apparatus 100 may include a management application (management program, system manager), etc. for smoothly operating various services and applications. For example, the system used by the display apparatus 100 may include a screen saver controller 1, and the system may count time for displaying the screen saver using the screen saver controller 1 and identify whether the counted time corresponds to a threshold time. According to an embodiment, when the counted time corresponds to the threshold time, the screen saver controller 1 may display the screen saver.

The application that is being executed in the display apparatus 100 according to an embodiment may transmit a reset request for the counted time for displaying the screen saver to the screen saver controller 1. Subsequently, the screen saver controller 1 may reset the counted time according to the reset request.

Since the counted time is reset according to the reset request, even if a user input is not received during the threshold time, the processor 120 may not display the screen saver.

FIG. 4 is a sequence view provided to explain a screen saver controller according to an embodiment.

Firstly, the screen saver controller 1 according to an embodiment counts time for displaying the screen saver after a user input is received (S410).

According to an embodiment, the screen saver controller 1 may receive a reset request for the counted time from the application that is being executed in the display apparatus 100 (S420).

Subsequently, the screen saver controller 1 may reset the counted time according to the reset request (S430).

For example, when a user input is received, the screen saver controller 1 may reset the counted time, and when the counted time reaches a threshold time as a user input is not being received during the threshold time, may display the screen saver.

According to an embodiment, the screen saver controller 1 may reset the counted time according to a reset request transmitted by the application even if a user input is not received.

Subsequently, the screen saver controller 1 may recount time for operating the screen saver (S440). For example, the screen saver controller 1 may count time for operating the screen saver again from 0 second after a reset request is received.

According to an embodiment, when the recounted time corresponds to a threshold time, (S450:Y), the screen saver controller 1 may display the screen saver (S460). In another example, when the recounted time does not correspond to the threshold time (S450:N), the screen saver controller 1 may continue counting of the time for displaying the screen saver (S470). In other words, the screen saver controller 1 may keep counting and increasing the time for displaying the screen saver.

FIG. 5 is a sequence view provided to explain an interface application according to an embodiment.

Firstly, the screen saver controller 1 (or the processor 120) according to an embodiment may identify state information related to an operation of the application that is being executed (S510).

Subsequently, the screen saver controller 1 may select one of ‘accept’ or ‘ignore’ regarding a reset request based on the state information. For example, when the screen saver controller 1 selects ‘accept’ regarding a reset request based on the state information, the screen saver controller 1 may reset the counted time according to the reset request received from the application.

In another example, when the screen saver controller 1 selects ‘ignore’ regarding a reset request based on the state information, the screen saver controller 1 may ignore the reset request received from the application and may not reset the counted time.

For example, the screen saver controller 1 includes an interface application 2, and may select one of ‘accept’ or ‘ignore’ regarding a reset request using the interface application 2.

In another example, the screen saver controller 1 may set the setting value of the interface application 2 that is distinguished from the screen saver controller 1, and the interface application 2 may select one of ‘accept’ or ‘ignore’ regarding a reset request according to the setting value.

Here, the interface application 2 may be one of various management applications (management program, system manager) running in the system, just like the screen saver controller 1. The interface application 2 is a term for convenience of explanation, and it can be called in various ways such as a valve interface, a reset request processing program, etc.

According to an embodiment, the screen saver controller 1 may adjust a setting value related to whether the interface application 2 that processes a reset request operates based on the state information (S520). For example, when the screen saver controller 1 adjusts a setting value so that the interface application 2 operates, the interface application 2 may accept a reset request received from the application.

In another example, when the screen saver controller 1 adjusts a setting value so that the interface application 2 does not operate, the interface application 2 may ignore a reset request received from the application.

In another example, the screen saver controller 1 may adjust a setting value so that one of ‘accept’ or ‘ignore’ regarding a reset request is selected, rather than to decide whether the interface application 2 operates.

For example, when the screen saver controller 1 adjusts a setting value so that the interface application 2 accepts a reset request, the interface application 2 may accept a reset request received from the application. In another example, when the screen saver controller 1 adjusts a setting value so that the interface application 2 ignores a reset request, the interface application 2 may ignore a reset request received from the application.

According to an embodiment, the application may transmit a reset request regarding a counted time (S530). When a reset request is received, the interface application 2 may accept or ignore the reset request according to a setting value (S540).

Firstly, when the interface application 2 accepts the reset request based on a setting value (S540), the screen saver controller 1 may receive the reset request (S550) and reset the counted time (S560).

In another example, when the interface application 2 ignores the reset request based on a setting value (S570), the screen saver controller 1 may not receive the reset request and keep counting without resetting the counted time. In addition, when the counted time corresponds to a threshold time, the screen saver controller 1 may operate the screen saver.

FIG. 6 is a view provided to explain acceptance of a reset request according to an embodiment.

According to an embodiment, the screen saver controller 1 may identify state information related to an operation of the application that is being executed.

Here, the state information may include information on a size of the application that is being executed on the screen of the display 110 (that is, information on a size of an area where the application is displayed on the screen of the display 110). Referring to FIG. 6 , when the size of the screen where the application that is being executed is displayed is equal to or greater than a predetermined size, the screen saver controller 1 may adjust a setting value of the interface application 2 so that a reset request transmitted by the application is accepted.

In another example, the state information may include whether the application is reproducing a video content. For example, the application may be a web browser, and the web browser may connect to various types of video content providing sites or video content streaming sites and reproduce video contents. The screen saver controller 1 may identify whether the web browser is reproducing a video content based on the state information of the application.

According to an embodiment, when it is identified that the application is reproducing a video content based on the state information, the screen saver controller 1 may adjust a setting value so that the interface application 2 accepts a reset request. The interface application 2 may accept the reset request transmitted by the application that is reproducing a video content so that the screen saver does not operate according to the setting value, and the screen saver controller 1 may reset the counted time.

In another example, when it is identified that the application is not reproducing a video content based on the state information, the screen saver controller 1 may adjust a setting value so that the interface application 2 ignores a reset request. The interface application 2 may ignore the reset request transmitted by the application that is not reproducing a video content, and the screen saver controller 1 may continue the counted time without resetting it.

In another example, the state information may include whether a current reproduction section of the content that is being reproduced by the application corresponds to a predetermined time section.

For example, the application that is being executed may be a video application (or a content player) that reproduces a video content. In this case, the state information may include information regarding the current reproduction section of the video content that is being reproduced by the video application.

When the current reproduction section of the video content is a predetermined time section, the screen saver controller 1 may adjust a setting value so that the interface application 2 accepts a reset request. For example, an important time section or a highlight time section may be predetermined according to metadata of the video content or a content provider, and when the current reproduction section of the video content corresponds to the predetermined time section, the interface application 2 accepts a reset request so that the screen saver does not operate according to the setting value, and the screen saver controller 1 may reset the counted time.

The above-described state information is only an example and is not limited thereto. For example, the processor 120 may control the display 110 to display a UI for setting whether the application transmits a reset request or a UI for setting whether to accept or ignore the reset request by the application, and the processor 120 may set whether the application transmits a reset request or set whether to accept or ignore the reset request transmitted by the application based on a user input for the UI.

FIG. 7 is a view provided to explain ignoring of a reset request according to an embodiment.

Referring to FIG. 7 , when the size of the screen of the application that is being executed is less than a predetermined size, the screen saver controller 1 may adjust a setting value of the interface application 2 so that a reset request transmitted by the application is ignored.

For example, when the size of the screen of the application is less than a predetermined size, the processor 120 may determine that efficiently managing power consumption or protecting light-emitting elements constituting the display 110 by providing a screen corresponding to the screen saver needs to be prioritized than resetting the counted time by accepting the reset request transmitted by the application.

In another example, as described above, when it is identified that the application that is being executed does not reproduce a video content based on the state information, the screen saver controller 1 may adjust a setting value so that the interface application 2 ignores the reset request. The interface application 2 may ignore the reset request transmitted by the application that is not reproducing a video content, and the screen saver controller 1 may continue the counted time without resetting it.

In another example, when the application that is being executed is a video application (or a content player) that reproduces a video content, the screen saver controller 1 may identify whether the current reproduction section of the video content is a predetermined time section based on the state information.

When the current reproduction section of the video content is not a predetermined time section, the screen saver controller 1 may adjust a setting value so that the interface application 2 ignores the reset request. Accordingly, when the current reproduction section of the video content does not correspond to a predetermined time section, the interface application 2 may ignore the reset request so that the screen saver operates according to a setting value, and the screen saver controller 1 may not reset the counted time.

FIG. 8 is a sequence view provided to explain a cycle of transmission of a reset request according to an embodiment.

For convenience of explanation, it is assumed that the interface application is set to accept a reset request and an application that is being executed transmits a reset request periodically.

Here, the application that is being executed in the display apparatus 100 means an application located in the foreground, but is not limited thereto. The application that is being executed in the display apparatus 100 may also include an application located in the background.

According to an embodiment, an application transmits a reset request (S820).

The interface application 2 may accept the reset request, and transmit the reset request to the screen saver controller 1 (S830). According to the reset request, the screen saver controller 1 may reset the counted time (S840), and recount time for displaying the screen saver (S850).

Meanwhile, the application may transmit a reset request again (S860). Here, the time difference between the operation of S820 and the operation of S860 may be less than a threshold time for which the screen saver controller 1 displays the screen saver.

For example, it may be assumed that when a user input is not received for a threshold time (e.g., 5 minutes), the screen saver controller 1 displays the screen saver. The screen saver controller 1 may recount time for displaying the screen saver after resetting the counted time in S840 and S850, and operate the screen saver when the recounted time reaches a threshold time. According to an embodiment, before the recounted time reaches the threshold time, the recounted time must be reset by receiving a reset request from the application and thus, the application needs to transmit a reset request in a period less than the threshold time.

According to an embodiment, the screen saver controller 1 may identify a time period during which the application that transmits a reset request transmits a reset request, and when the identified time period exceeds a threshold time, the screen saver controller 1 may set the application to transmit a reset request in a period less than the threshold time.

Meanwhile, the screen saver controller 1 recounts time for displaying the screen saver after resetting the counted time in S840 and S850, and when a user input is received before the recounted time reaches the threshold time, may reset the recounted time.

In another example, when the recounted time reaches the threshold time, the screen saver controller 1 may display the screen saver.

FIG. 9 is a view provided to explain a specific application according to an embodiment.

Referring to FIG. 9 , when it is identified that at least one application that is being executed in the display apparatus 100 corresponds to a specific application, the processor 120 may not display the screen saver regardless of whether a reset request is received.

For example, the screen saver controller 1 (or the processor 120) may include a list of specific applications for not displaying the screen saver. When it is identified that at least one application that is being executed in the display apparatus 100 is included in the specific applications according to the list, the screen saver controller 1 may not display the screen saver.

In another example, the screen saver controller 1 may include an interface application disable window 3, and the interface application disable window 3 may inactivate the operation of the interface application 2.

For example, when it is identified that at least one application that is being executed in the display apparatus 100 is included in the specific applications according to the list, the screen saver controller 1 may use the interface application disable window 3.

When a reset request is received from the application (S920), the interface application disable window 3 may transmit the reset request to the screen saver controller 1 regardless of a setting value of the interface application 2 (i.e., by skipping the interface application 2) (S930).

Accordingly, even if the interface application 2 is set to ignore a reset request, the interface application disable window 3 may transmit the reset request received from the application to the screen saver controller 1 (S930), and recount time (S950) after resetting the counted time (S940).

Here, the interface application disable window 3 may be one of various management applications (a management program, a system manager, etc.) running in a system, such as the screen saver controller 1 and the interface application 2. The interface application disable window 3 is a term used for convenience of explanation, and it may be referred to as various terms such as a valve interface, an inactivation program, etc.

Meanwhile, according to various embodiments, each of the screen saver controller 1, the interface application 2 and the interface application disable window 3 operates under the control of the processor 120 and thus, the operation of each of the screen saver controller 1, the interface application 2 and the interface application disable window 3 in the above-described example may be implemented as the operation of the processor 120 or each of the various operations of the processor 120 may be implemented by being divided into the operation of each of the screen saver controller 1, the interface application 2 and the interface application disable window 3.

Here, the specific application may mean an application that transmits a request for activating the interface application disable window 3, an application registered with a list included in the screen saver controller 1, and the like. In another example, the specific application may mean an application identified by the screen saver controller 1 as corresponding to a specific type. For example, when the application that is being executed in the display apparatus 100 is a game application, a content player, or the like, the screen saver controller 1 may directly receive a reset request sent by the application (for example, without going through the interface application 2) using the interface application disable window 3.

FIG. 10 is a view provided to explain a screen protection function according to an embodiment.

The screen saver controller 1 (or the processor 120) according to an embodiment, when it is identified that at least one application that is being executed corresponds to a specific application, may not display the screen saver regardless of whether a reset request is received.

The screen saver controller 1 (or the processor 120) according to another embodiment may execute a screen protection function instead of displaying the screen saver.

In another example, when a reset request is received from at least one application that is being executed, the screen saver controller 1 may execute a screen protection function in an area except for the area where at least one application that is being executed on the screen of the display 110 is displayed.

For example, the screen saver controller 1 may execute a screen protection function when the interface application ignores a reset request according to a setting value and a reset request is received from the at least one application that is being executed.

Referring to FIG. 10 , the screen saver controller 1 may execute a screen protection function in an area except for the area where at least one application (e.g., a specific application) that is being executed on the screen of the display 110.

Here, the screen protection function may mean a mode for adjusting the luminance, chroma, brightness, etc. of the remaining area except for the area where at least one application (e.g., a specific application) that is being executed is displayed on the screen of the display 110 to a preset value or less.

For example, the screen protection function may prevent the lifespan of an element from being shortened by adjusting the luminance of the remaining area except for the area where the application providing a video content (e.g., a specific application) on the screen of the display 110 is displayed to a preset value or less or by turning off a self-luminance element corresponding to the remaining area, there by efficiently managing power consumption.

FIG. 11 is a flowchart provided to explain a controlling method of a display apparatus according to an embodiment.

The controlling method of a display apparatus according to an embodiment may include counting time for displaying the screen saver after a user input is received (S1110).

Subsequently, when the counted time corresponds to a threshold time, the screen saver is operated to display a screen corresponding to the screen saver (S1120).

Here, the counting operation of S1110 includes identifying state information related to the operation of the application that is being executed in the display apparatus, adjusting a setting value related to the interface application that processes a reset request for resetting the counted time based on the state information, and when a reset request is received from the application, selecting one of ‘accept’ or ‘ignore’ regarding the reset request through the application.

The state information according to an embodiment includes information regarding whether the application that is being executed is reproducing a video content, and the adjusting operation includes, when it is identified that the application that is being executed is reproducing a video content based on the state information, adjusting a setting value so that the interface application accepts a reset request, and when it is identified that the application that is being executed is not reproducing a video content, adjusting a setting value so that the interface application ignores a reset request.

The application according to an embodiment is a video application that reproduces a video content, the state information includes information regarding the current reproduction section of the video content that is reproduced in the video application, and the adjusting operation includes, when it is identified that the current reproduction section of the video content that is reproduced in the video application is a predetermined time section based on the state information, adjusting a setting value so that the interface application accepts a reset request, and when it is identified that the current reproduction section of the video content that is reproduced in the video application is not a predetermined time section based on the state information, adjusting a setting value so that the interface application ignores a reset request.

The controlling method according to an embodiment may further include setting the application to transmit a reset request in a period less than a threshold time.

The controlling method according to an embodiment may further include, when it is identified that a specific application is included in at least one application that is being executed in the display apparatus, not displaying the screen saver regardless of whether a reset request is received.

Here, the controlling method may further include executing a screen protection function in an area except for the area where at least one application that is being executed on the screen of the display is displayed.

The controlling method according to an embodiment may further include, when a subsequent user input is received after a user input is received, resetting the counted time, recounting time for displaying the screen saver after the subsequent user input is received, and when the recounted time corresponds to a threshold time, displaying the screen saver.
